I did Exercise 3.1 by commenting the code. However while doing Exercise 3.2 onwards part (a) I am getting some errors. I had pasted my code below the pictures.

Your assignment instructs you to write a MATLAB function image_sample but you have written a MATLAB script image_sample. See this documentation page for some information about the differences between functions and scripts.

The code about loading an initializing variables needs to go in LAB3.m or similar name.
The first line of image_sample.m needs to start with the word "function".
The function in image_sample.m needs to be called from outside of image_sample.m and that cannot happen if image_sample.m is a script.
